I have enjoyed this book: “CSS. The Missing Manual” and would recommend it to those looking for learning CSS.
There are a lot of hands-on exercises that go along with the instruction.
Have a nice reading.
I've been working in the IT industry since 1999. I started from Oracle PL/SQL programming and then I became a software architect for serum.com.pl, which is a Web_Toolkit AKA Apex based system. In the subsequent years, I've shifted my focus to SOA, BPM, EA and IT architectures. At the moment, I'm a solution architect working in one of the biggest Lithuanian IT companies.
